If you need even more evidence that Samsung is looking for ways to make a bigger impact in the world of wearable technology, a new patent has surfaced that describes an AR keyboard input method designed for use in wearable devices like computerized glasses. The patent was originally filed last year at the World Intellectual Property Organization, as well as Korea’s intellectual property office.

Samsung's AR keyboard works by having the three sections of each of your fingers (except the thumb) represent different input characters.

According to Samsung’s patent filing, current computerized glasses and smartwatches have limited space for more traditional means of input, like a standard keyboard or a touchscreen. Samsung says that voice recognition is the obvious alternative in these situations, but notes that there are limitations here as well.

Samsung’s solution is to bring us an AR keyboard, which works by having the three sections of each of your fingers (except the thumb) represent different input characters. Different layouts can even be used, depending on your choice of language and whether or not you were using one or both hands.

Controlling the keyboard is as simple as selecting the sections of your finger using your thumb, with an on-screen representation of your hand guiding you through the process (as seen below). Alternately, a headset with augmented reality overlay abilities could also project the characters directly onto your fingers (seen above).

So how would the wearable device know what parts of the finger you are touching? The idea is that a camera would track and analyze your finger movements and translate them accordingly.

Is this a practical solution?

We can certainly see where an AR keyboard could come in handy, but there’s some potential downsides here.

First, this method would require a high-end camera in order to properly track your finger movements, which would add to the costs. Second, the device would have to leave the camera and display running while you type, and this could lead to poor battery life. It’s also pretty likely that Samsung’s AR keyboard would have a fairly sharp learning curve.

Even if you get past all of that, you’d sort of look a bit like a crazy person jittering your fingers around in strange patterns as you wrote out messages and other commands. Then again, what modern technology doesn’t make us look a bit crazy? Bottom-line, this is a cool idea, even if far from a perfect one.

It’s also important to point out that just because Samsung has a patent for the technology doesn’t mean they are actively planning on bringing us a device that uses it. What do you think, like Samsung’s idea for an AR keyboard or not? Let us know what you think in the comments.
